Prince Harry of Wales photographed naked in Las Vegas, TMZ claims

Prince Harry and Kate Middleton (a.k.a. Catherine, Duchess of Cambridge) applaud in the stands of the Olympic stadium during the closing ceremony of the 2012 London Olympic Games in London on August 12, 2012.

What happens in Vegas stays in Vegas... unless you're third in line to the British throne and lose at a game of strip billiards, it seems.

Prince Harry of Wales has apparently been caught with his pants down, again — this time literally, in front of several naked women in a Las Vegas hotel suite.

Gossip website TMZ published photos purporting to be the 27-year-old party loving prince cupping his... ahem, crown jewels, and bear-hugging a naked woman from behind as she held a pool cue.

Or, as TMZ put it, they are of Prince Harry "getting BARE ASS NAKED during a game of strip billiards."

TMZ reported that the prince "went down to the hotel bar and met a bunch of hot chicks ... and invited them up to his VIP suite."

That's when "things got wild," the site wrote.

Prince Harry was in Vegas after concluding his royal duties at the London Olympics, which included presiding over the Closing Ceremony.

While in Vegas, Prince Harry also challenged Olympic gold-medalist Ryan Lochte to a race during a pool party attended by 5,000 people — and Jennifer Lopez — according to London's Daily Mail.

The prince, who was reportedly wearing jeans and given a head start, reportedly lost to Lochte in the race, organized for 2 a.m. after the pair had partied the night away at the Wynn Hotel's XS nightclub.

The so-called party prince was caught out numerous times as a teenager for his drunken antics, which included once wearing a Nazi costume to a fancy dress party in London. The BBC covered the furor at the time.

TMZ quoted a spokesperson for the royal family offering "no comment" the latest apparent royal slip-up.
